**An agent can connect on its own if it already holds `QR_TOKEN`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Quality 77/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: list_folders (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_subdomain (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_subdomain (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 2,129 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 98 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: @open-qr/mcp@1.0.2 resolved: 98 packages

- tools: 20, about 2,129 tokens to load them all
- tool set hash: e4a930677ee6e2f10f6a83146b272fec
- badge: [![protogrid quality](https://protogrid.dev/badge/uk.openqr/qr.svg)](https://protogrid.dev/servers/uk.openqr/qr)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (20)

- `bulk_create_dynamic_qr`: Create up to 200 dynamic QR codes at once. Requires an OpenQR API key.
- `clear_subdomain`: Release the branded subdomain. Codes stay live on the plain short link; only the {name}.oqr.to form stops resolving. The name becomes claimable by someone else. Requires an OpenQR API key.
- `create_dynamic_qr`: Create an editable (dynamic) QR code whose destination you can change later without reprinting. Requires an OpenQR API key.
- `create_folder`: Create a folder to organise codes. Requires an OpenQR API key.
- `create_link_alias`: Create an extra short link (link alias) that resolves where one of your dynamic codes points: share a different slug per channel while the QR keeps its own slug, so QR scans and link clicks are counted separately. Free accounts have no alias allowance; Pro includes 10. Requires an OpenQR API key.
- `create_static_qr`: Save a static QR code to your library from structured fields: wifi, contact (vCard), email, SMS, WhatsApp, location, text, phone or URL. Static codes bake the content into the code itself — no short link, no scan analytics, not editable later. Render the returned payload with generate_qr. Requires an OpenQR API key.
- `create_theme`: Save a reusable style theme. `style` is a QR style object (fgColor, bgColor, dotType, cornerSquareType, etc.). Requires an OpenQR API key.
- `delete_dynamic_qr`: Permanently delete a dynamic QR code. The short link stops working. Requires an OpenQR API key.
- `delete_folder`: Delete a folder (its codes are un-filed, not deleted). Requires an OpenQR API key.
- `delete_theme`: Delete a saved theme. Codes already styled with it keep their look. Requires an OpenQR API key.
- `generate_qr`: Generate a static QR code from any text/URL. Returns a PNG image (or SVG markup). Requires an OpenQR API key.
- `get_dynamic_qr`: Get the full details of one of your QR codes by id: destination, short link, label, type, tags, folder, status and created date. Requires an OpenQR API key.
- `get_scans`: Get scan statistics for a dynamic QR code. Requires an OpenQR API key.
- `get_subdomain`: Show the branded subdomain on this account ({name}.oqr.to). Reports whether it is currently suspended — a suspended subdomain redirects to the plain short link instead of serving, which happens when a Pro plan lapses. Requires an OpenQR API key.
- `list_dynamic_qr`: List your dynamic (editable) QR codes — id, short URL, destination, label and status. Requires an OpenQR API key.
- `list_folders`: List your folders (id and name). Requires an OpenQR API key.
- `list_link_aliases`: List the link aliases of one dynamic code. Requires an OpenQR API key.
- `list_themes`: List your saved style themes (id, name) — apply one by passing its id or name as `theme` to generate/create/update tools. Requires an OpenQR API key.
- `set_subdomain`: Claim or change the branded subdomain so codes also resolve at {name}.oqr.to. Pro only. Codes keep working on the plain short link either way, so changing this never breaks anything already printed. Requires an OpenQR API key.
- `update_dynamic_qr`: Edit a dynamic QR code: change its destination, label, custom short link (slug), tags or folder. Pass only the fields you want to change. Requires an OpenQR API key.
